In a statement Monday, Labor Secretary Silvestre Bello said "temporary suspension of business operations should not and must not result in the termination or separation of any employee."

Bello has given notice to employers that they either follow the "no work, no pay principle" or "require the employees to go on forced leave by utilizing their leave credits, if any."

"Employees are expected to be recalled back to work upon the lifting of the temporary closure of Boracay island," he added of the looming six-month closure staring April 26.

The statement said the advisory was for "strict observance and compliance."

The government said it will give financial help to more than 30,000 affected workers due to the closure.

On Sunday, Bello told CNN Philippines the DOLE will employ 5,000 informal employees and indigenous peoples (IPs) working on Boracay, as part of its P60 million emergency employment program where these workers would help in the island's cleanup.

Bello said the Departments of Social Welfare and Development, Interior and Local Government, Public Works and Highways, and the Commission on Higher Education are also coming up with their own program to address the problems of the displaced workers.

He added possible employment of skilled workers and non-Boracay residents will be addressed by other agencies.
